Description

Title: Video-supported rebuilding of dialysis machines

description

The present invention relates to a calculation unit, an image support system for a dialysis machine or for another medical device and a method and a computer program for calculating a screen output to the accompanying

Operation support for the dialysis machine.

Known modern medical devices, particularly dialysis machines, such as the 5008 hemodialysis machine from Fresenius Medical Care, require a sequence of operations and actions to be performed on the machine or on attached equipment, such as the machine, to upgrade the machine or operate the machine. one

Heparin pump, must be performed. The user is supported and guided in the operating steps to be executed via a suitable display on a display of the machine. The display may be e.g. to a touch-sensitive screen, a touch screen, to control the device and to input and output of data. For the touch-sensitive user interfaces of dialysis machines

usually uses a capacitive sensor technology. A touchscreen with a capacitive sensor technology is described in more detail, for example, in DE10 2011 01 1 769 A1.

The hemodialysis system comprises as a central unit a dialysis machine which serves to continuously direct blood of the patient into an extracorporeal technical circuit module through a blood chamber of a filter or a dialyzer. The blood chamber is separated by a semipermeable membrane from a dialysis fluid chamber. The

Dialysis fluid is flowed through by a blood electrolyte containing dialysis fluid. The substance concentration of the dialysis fluid corresponds to the concentration of the blood of a healthy person. During the treatment, the patient's blood and the dialysis fluid on either side of the membrane are generally passed countercurrently at a predetermined flow rate. The urinary substances diffuse through the membrane from the blood chamber into the chamber for dialysis fluid, while at the same time in the blood and in the dialysis fluid existing electrolytes from the chamber higher

Diffuse concentration to the chamber of lower concentration. By applying a transmembrane pressure, the metabolism can be additionally influenced.

Replacement Blade (RULE 26) The extracorporeal blood circulation module and the device itself comprise several technical components, such as substituate pumps, valves, throttles, pressure sensors and technical elements and devices, such as external connections, push handles, fan filters, a power connection, hydraulic connections with flaps, etc. For upgrading and operating the dialysis system The above-mentioned technical components and devices must be operated - often in a coordinated sequence with several operating steps. When carrying out operating steps on the various technical equipment of the machine, it can lead to incorrect conditions that affect the operation of the dialysis machine or even impossible. It is therefore important to ensure correct and efficient operation. Errors should be detected and avoided.

For this purpose, it is known in the prior art to output on a monitor of the dialysis machine certain instructions with which the user in the execution of

Operating steps is supported. The hints may also include videos and / or animations.

However, it proves to be disadvantageous in the known systems that the representation of a video on the monitor can only be carried out completely. Frequently, however, there are individual passages or sections in a video that represent critical or critical or difficult operating steps. The user would like to request specific support for these operating steps and is less or not interested in the video clips shown before and after. In order for the user to navigate to these critical locations, he must pause the entire video and manually repeat the appropriate passage. This is associated with effort.

In order to give the user more freedom, it is desirable that means are provided with which one can navigate specifically to individual sequences of the video or a sequence of images.

The operation of medical devices is associated with the danger of contamination by germs and pathogens as soon as the user has to make inputs on a touch-sensitive monitor. There is therefore a need to minimize or eliminate the need for user input to control display of help instructions. Since the operation of the device sometimes concerns life-sustaining measures for the patient, the guarantee of a correct operation of the device with all

Preparatory steps of high importance for the safety of the system. In this context, the invention seeks to improve the human machine interface.

The present invention has therefore set itself the task of overcoming the disadvantages described above and to improve the operation of dialysis machines and other medical equipment and in particular to make it safer. Furthermore, the electronic support means in a device operation, which may require several operations on possibly different resources, improved and

be accelerated. An output result is to be provided with improved image support by moving images, which can be controlled free of any risk of contamination.

This object is achieved by a calculation unit, a medical device with such a calculation unit, an image support system and a

Method and solved by a computer program according to the enclosed independent claims.

According to a first aspect, the invention relates to a computer-based

Calculation unit for calculating a screen output (in particular for display on a monitor) for assisting operation in the operation of a medical device, in particular a dialysis machine (for example an operation with a sequence of operating steps during the upgrade). The calculation unit is above a

Image interface with a graphics memory in data exchange, in which a lot of image sequences (eg videos for instructions in the device operation) is stored. The image sequences in the graphic memory are not monolithic or as a block but stored in a structured format. The structured format allows a more flexible access to individual sequences of the image sequence, so that individual sections of the respective image sequence, so-called (sequence) sequences, each individually, are independently addressable and separately addressable. An identification signal for identifying at least one sequence in the stored image sequences is provided on the calculation unit. The calculation unit can for this purpose include a control interface which is intended to capture control data for controlling the screen output (in particular for determining an output mode). Furthermore, the calculation unit is intended to control the Access image interface with the detected identification signal to the graphics memory to read in response to the at least one identified sequence and from it - possibly on the basis of the detected control data - to calculate the screen output with the identified sequence. The control interface is preferably formed without contact, which reduces the risk of contamination and germ transmission.

In essence, the present invention relates to an electronic module which can be used in combination with a medical device and which makes it possible to support complex operations with a sequence of operating steps by an operation time adapted and adapted to the individual operating step output of video sequences. In this case, an operating procedure (for example inserting a tube) comprises a sequence of operating steps to be executed sequentially. Accordingly, this is represented in the specific formatting of the stored image sequence: A sequence of images (e.g., an animated video) accordingly comprises a sequence of sequences. This has the advantage that the user can be supported very specifically in his device operation. The time sequence and duration of the execution of the operating steps is thus not tied to the time sequence and duration of the display of the video sequences and can be decoupled from it. So the user can e.g. the first steps faster and completely without

Perform video support, perform other operations in parallel with video output, and perform complicated steps to replay the assigned sequence multiple times.

In a preferred embodiment of the invention, the control interface is a man-machine interface (MMI) and implemented such that germ transmission can be avoided. In particular, it may be non-contact (e.g., gesture control, vibration based, and / or voice control). Alternatively, it may be decoupled from other equipment components (e.g., footswitches) to avoid contamination.

Another aspect of the invention relates to the use of the described

Calculation unit for controlling a monitor for outputting a screen output for assisting in device operation. The monitor can be connected to or integrated into the medical device. The monitor can also be connected as a separate unit via interfaces to the calculation unit. In a second aspect, the invention relates to an image support system for assisting operation in the operation of a medical device, in particular a dialysis machine, comprising:

a monitor intended to display a calculated screen output; and

- A calculation unit described above, wherein the monitor of the

Calculation unit is controlled.

In the image support system, as described above, the monitor may be connected to or integrated with the medical device. The control interface is preferably decoupled from the monitor operation (non-contact).

Preferably, the medical device may include a sensor unit on individual resources to automatically determine an operating state of the device, so that the identification signal can be automatically calculated from the determined operating state. For example, if the user has already performed the first steps and is now faced with the execution of a complicated operating step on a resource, this can be detected directly on the device via the sensor unit. The calculation unit can automatically calculate from the sensor data of the sensor unit and the access to a rule base, which sequence is assigned to the determined operating state and in particular the following operating step and is to be identified for calculating the screen output. In the rule base, assignments of sensor data, metadata and sequences can be stored.

The invention will be described below with reference to the task solution according to the method and thus with reference to the method. As mentioned features, advantages or alternative embodiments are also claimed to the other

Transfer items and vice versa. In other words, the

representational claims (for example, to a system or on the

Calculating unit are addressed) with the features that are in

Are described or claimed in connection with the method. The corresponding functional features of the method are thereby formed by corresponding physical modules, in particular by electronic circuit components or microprocessor modules of the system or the device, and vice versa. In a further aspect, the invention thus relates to a method for calculating a screen output in support of an operation in the operation of a

medical device, in particular a dialysis machine, in which a graphics memory is provided in which a set of image sequences are stored in a structured format such that each image sequence comprises a sequence of individually or dedicated addressable image sequence sequences, comprising the following method steps:

- Providing an identification signal for identifying a sequence in the image sequence;

- Optional: capture control data to control the screen output;

Accessing the graphics memory with the provided identification signal to directly address and read the sequence (s) to be identified in the image sequence;

- Calculating the screen output with the read-in identified sequence and optionally based on the provided control data. If no control data could be recorded or entered without errors, standardized control data stored in advance will be used.

In a preferred embodiment of the invention, the identification signal is automatically calculated as a function of a sensory detected operating state of the medical device. The operating state can be detected by a sensor unit. If e.g. the user is currently busy to upgrade the peristaltic pump, this can be detected automatically via an example, optical sensors. The identification signal for identifying the sequences assigned to the operating procedure here becomes automatically dependent on the operating state

(Hose pump upgrade) determined. Without an input of the identification signal by the user, this can also be calculated automatically. This has the advantage that the user is supported more efficiently in his activity without additional measures.

For the input of the identification signal two variants are provided:

1. The identification signal can be manually via a user input from the

User can be entered. For example, this can be a

Interaction interface on a monitor, for example on the monitor of the

Dialysis machine, are provided, on which the user the identification signal enters, for example, via the operation of an input field on a touch-sensitive display. For this purpose, in a preferred embodiment, different identifiers (for example graphical icons or names) can be displayed on the screen surface, from which the user can then select an input by clicking. For example, identifiers for different sequences could be represented here (for example in the form of

Thumbnails), as a miniaturized graphic representation of a sequence, the

for example, may include the first segment of the sequence. If the user then selects a thumbnail representation of a sequence, then this sequence is considered selected and is transferred to the calculation unit as an identification signal or identification data record.

2. An alternative way of entering the identification signal is to use so-called metadata. Metadata is additional data stored in an associated manner with the sequences in memory. It is also possible to store several metadata about a sequence.

Metadata includes, for example, time information (when a specific operating step is to be carried out), the operating resources to be used (for

Example peristaltic pump) and may optionally include other data sets. A set of metadata records is now stored in a memory of the calculation unit for each sequence. This makes it possible that a sequence can also be identified by the specification of metadata. If the user selects certain metadata from a set of predefined metadata sets on a user interface, then these are detected and from this the identification signal for identifying the sequence can be automatically calculated. It is advantageous if the memory has an additional interface with the assignment between metadata and sequences in order to ensure that the assignments are also independent of

To change the procedure. In particular, with the additional

Interface the process changed and adapted to the circumstances of each user or the device.

3. A third way to detect the identification signal consists in a

automatically calculating it based on sensor data collected on the medical device. These may, for example, be optical sensors and / or position sensors which are intended to detect the operation and an operating state of the device. If one or more sensors If the user has just begun to upgrade the device, then he will automatically be shown those sequences that relate to the determined operating state and that deal with the first steps for upgrading the device.

In a further embodiment, it is provided that an image sequence (for example in the form of an animation or a video) is already displayed on the monitor. Then, an interaction interface can additionally be provided on the monitor, via which the user can control which sequence he would like to see next. For this purpose, for example, fields of activity can be represented which provide a repeated display of the sequence, a skip, a transfer to the next sequence, a return to the previous sequence, a jump to the beginning of the image sequence and a jump to the end of the image sequence and optionally further control options , In this embodiment, the screen output may include two segments:

1. An image segment used to represent the set of identified sequences, and

2. an interaction interface through which the user can control the representation of the sequences (with commands as described above NEXT, STOP,

SKIP etc.).

In a preferred embodiment, control data is collected, but this is not necessarily necessary, if no control data is acquired, then predefined control instructions are used. The control data preferably includes an output mode for the identified sequence (s) for the identified sequences, if multiple sequences have been calculated for the screen output. This is

especially possible if, for example, in the graphics memory more

Sequences are stored that relate to a specific operation. The output mode, for example, indicates the output format in which the sequences are to be output on the monitor. The output mode may refer to a sequence or a group of sequences. Thus, for example, it can be determined that first the first sequences are to be played in slow motion, while the following sequences are to be displayed at normal speed and again other sequences in an accelerated display. The output mode may also indicate, for example, that certain sequences in a

Repeat loop to be displayed. In addition, additional information provided how often the repetitions are to be displayed. In addition, the control data may include other data, for example, indicate that the screen output next to the sequence of pictures (for example, video) yet others

Include data forms, such as data in textual form, audio data, etc.

In a further preferred embodiment of the invention, the control data is entered or detected via a non-contact interface. The interface for detecting the control data can be designed as an interaction interface, via which the identification signal is also detected. However, this is also not mandatory. In another embodiment, two different interfaces for detecting the control data and for detecting the identification signal may be provided. Specific embodiments thereof are set forth in the detailed description of the figures

Explained referring to the figures. The interface for inputting the control data (control interface) may be an interface for detecting gestures (optical

Interface) or an interface for detecting voice input. This has the technical advantage that no direct contact with the input of the control data is necessary. This can be avoided contamination of the medical device or other associated components advantageously. If the control data are not entered manually by the user, they can also be entered locally on the

Calculation unit can be calculated from other imported data. Alternatively, preconfigured control data may be provided in a memory which, in the event of missing or erroneous input of the control data, may be used to calculate the screen output.

In principle, the solution proposed here makes it possible for the user to freely select the display of the supporting operating instructions which are represented in the individual sequences and, in particular, to instruct him to display them as a function of the temporal progress of his operation. In addition, it is possible for the user to select sequences from a sequence of images dedicated to screen output

should be considered, while the other sequences should not be displayed. This has, for example, the background that operations for which the user does not need support, also not displayed, while complicated operations, for which he would like to receive a visual support, optionally in a freely selectable output mode (for example, repeatedly or in Slow Motion) can be displayed. Thus, the user can customize the output of supporting notes individually to his personal operation and operating time. It is essential that the individual sequences can be identified independently of one another (that is to say intended for output) and, secondly, that different output modes can be determined for the respective sequences. One

For example, output mode may specify that the sequence of sequences (which more meaningfully corresponds to a sequence of operations to be performed) in precisely this identical sequence is also considered for display on the monitor. In the screen output, the transition or switching from a first sequence to a subsequent sequence can be triggered automatically as soon as the first sequence has been completely displayed. Alternatively, however, it is also possible to automatically stop after the complete execution of a sequence. If the user then wants to display another sequence for display, the user must input a trigger signal. The trigger signal may be part of the control data, for example. In the simplest case, the trigger signal can be entered by pressing a NEXT or BACK key. This causes execution of an increment or decrement instruction in the memory to automatically switch to the next or previous sequence. The above

described control mode in which the full output of an identified sequence requires a trigger signal to represent another screen output, offers the advantage that a very fine time adjustment of the screen display is possible. On the other hand, however, this also requires multiple inputs from the user. In order to reduce the effort at this point (in particular for user input on the part of the user), it is provided in a preferred embodiment of the invention that the method can be activated and deactivated. For activation, a start signal can be detected and / or for deactivation can be used to detect a stop signal. This has the advantage that the method can be adapted even more flexibly to the particular application, for example, by simple and routine operations without

Screen outputs can be executed.

In another preferred embodiment of the invention, meta information is additionally stored in an associated manner for each sequence in the graphics memory. This makes it possible for a sequence not only directly via its memory address in

Memory, but also indirectly via the associated meta-information can be addressed. The storage is preferably carried out in the form of a relational database and the access to the database may relate not only to the use of the identification signal and parameters of the metadata. For example, it is possible to identify all those sequences that have a specific query, for example in the form of a database query Operating resources (for example, dialysate container) relate and to use this to calculate the screen output.

An important feature of the proposed solution is the fact that the individual sequences of the image sequence are independently and individually addressable in a dedicated way. Therefore, in a preferred embodiment, the sequences in the graphics memory are generated by a method of non-linear editing.

The method is computer implemented and can be used in the

Calculating unit to be formed. In this case, the computer program is loaded into an internal memory of the (digital) calculation unit and comprises software routines with which all steps of the method described above are executed when the software routines on the calculation unit are executed. Another task solution thus provides a computer program to carry out all

Process steps of the method described in more detail above, when the

Computer program is executed on a computer, an electronic or medical device. It is also possible that the computer program is stored on a readable for the computer or the electronic or medical device medium.

Another task solution is a computer program product for a medical device that is loaded or loadable into a memory of a computer or an electronic or medical device with a computer program for carrying out the method described in more detail above, when the computer program on the computer or the electronic or medical technology Device is running.

The computer program product may be stored in an internal memory of a digital memory

Control unit to be loaded.

The terms used in this application are explained in more detail below.

The operation of the medical device is usually at different

Resources of the same and includes a sequence of consecutively executed

Operations performed on the same or different equipment. To assist the user in the operation, a screen output is generated which dynamically in response to an identification signal and / or

Control data is calculated. The operation may concern, for example, the upgrade of the medical device, in particular a blood treatment device, a hemodialysis Dialysis machine, a peritoneal dialysis machine or other medical devices. The screen output for this purpose comprises an image component which is designed to represent one or more identified image sequence sequences.

The image sequences may preferably be individual frames of a video, an animation or the like. The image sequence is therefore a moving image that may be enriched with other data, in particular text data (for example, annotations with further instructions). An image sequence thus comprises a sequence of individual images.

A sequence is a section or a part of the image sequence, in particular a

Video clip. Preferably, an image sequence is structured such that it comprises a sequence of sequences. The individual sequences are individually and independently addressable. A first sequence can thus be addressed and identified independently of another sequence in order to be used for calculating the screen output. Each sequence contains or represents different

Operating steps.

The operation of the device requires a sequence of individual operating steps. The image sequence is structured to include (also) a sequence of (sequence) sequences. Different approaches can be used to generate the sequences and store them in graphics memory. Preferably, a sequence of operations has a correspondence in the sequence of the sequences. Different measures can be used to generate the sequences. As a rule, the sequences are generated by extracting individual sections from a sequence of images according to predefined rules. The length of the cutout can be done to the

Operating steps are adapted. This may be stored in a rule base with rules defining the length of the sequences and / or the content of the sequences. In a very simplified example, a first sequence may include first, second, and third images, while a second sequence may include image 4 through image 5 and a third sequence may include image 6 through image 10.

The inputs of the user (for example control data, identification signal) are preferably detected without contact, for example by voice inputs or gestures, in order to avoid the transmission of germs. Alternatively, a foot switch may be provided, if only simple operating measures are required (for example for sequencing from sequence to sequence, the operation of the footswitch may be provided).

An identification signal is a digital record used to uniquely address a graphics memory address (register) with a sequence stored therein.

The control data serve to control the calculated screen output. The control data identifies an output mode for the identified sequence. The output mode may include several parameters, in particular an output speed (slow motion, accelerated, etc.), a resolution and other technical parameters (in particular

Focusing on a specific image section, output direction of the sequence (relative to the temporal sequence, especially forward or backward).

The computing unit is an electronic unit that may be implemented in hardware as an integrated circuit (e.g., FPGA, field programmable gate array) and / or software. The calculation unit is used to calculate signals for a

Screen output. The calculation unit can be implemented directly in a graphics card or in a graphics chip or indirectly on a processor unit which is in communication with the graphics card and with a monitor. The graphics card writes data for the monitor to a graphics memory, which is usually designed as RAM (random access memory). The processor unit and / or the graphics chip or the graphics card read the memory to bring the stored data - usually via a digital-to-analog converter - on the display for display. Optionally, a video adapter may be implemented which includes the digital signals of the computing unit and / or a

Application program, store them in memory (e.g., Video RAM) and convert them to an analog signal (using a D / A converter). The

Calculation unit is used for the control state-dependent control of the monitor to display the dynamically generated screen output. The screen output can be controlled via sensor data of a sensor unit depending on the operating progress or state. The control data are converted by means of a control logic of the calculation unit into control commands for state-dependent control of the monitor for signal output.

The sensor unit comprises a plurality of sensor modules. The sensor modules in turn comprise several sensors. The sensor modules are installed on the dialysis machine, preferably at several positions in the device, and on all or selected operating means of the device and / or on the respective interfaces between the device and operating means. The sensors are preferably installed as sensors of different types of sensors and include not only optical sensors, acoustic sensors, position and / or proximity sensors, temperature sensors, Hall sensors and other types of sensors but also switches, buttons and / or potentiometers etc.

The medical device requires to operate a variety of technical equipment, such as pumps, hoses, dialysis filters in dialyzers, terminals or other mechanical and / or electronic units that need to be connected to the device or are already integrated into this. The equipment may also be intended

To include disposable items, such as hoses, filters, disposable syringes, etc. According to the invention, each resource is formed with at least one sensor. The equipment must be operated. For example, a heparin syringe must be properly inserted into the designated pump on the device and connected before it can be put into service. It is thus a sequence of specific operations on the device and / or the resources required. This sequence is inventively by the

Sensor unit checked. The totality of all sensor signals represents one

Operating state of the device or the machine with its equipment. Upgrading the dialysis machine with the blood tubing system may be accomplished e.g. take place only when the cover is open. For this purpose, a sequence can be output according to the invention, which indicates that the cover is to be opened. This can be done in a simple text hint that supports the user in a specific case-specific condition.

A significant advantage of the solution proposed here is the fact that the individual sequences can be used individually for screen output. Different output modes can be provided for the respective individual sequences.

For example, a first sequence can be repeated slowly and a second sequence repeated and a third sequence can be accelerated.

In other words, the output of the individual sequences can be calculated independently of one another and with different output modes. Another advantage is the fact that the screen output can also be changed dynamically during the output. This is made possible by the fact that control data or changed control data can also be entered and taken into account during the screen output. In other words, it may be that a calculated screen output for displaying a sequence in a first output mode (normal display) is modified by entering a modified control data set. If, for example, the user with new control data signals that he is currently a slowed representation of

To instruct screen output, this signal is detected by the calculation unit and converted to the modified calculation of the screen output, so that immediately the currently displayed sequence can be displayed in slow motion. After complete output of the respective sequence, the user has the opportunity to decide how he wants to proceed and whether he would like to have the respective sequence repeatedly displayed, for example, or whether he would like to switch to the next or to another sequence. Thus, in this embodiment, the control data always refers to a specific sequence. The control data can thus be sequence-individual in order to be able to image different output modes for the individual sequences. It is also possible to execute any jumps between the sequences which do not necessarily correspond to the sequence of the operating steps. This has the advantage, for example, that the user can instruct the display of already executed and converted sequences even in an advanced operating stage.

In a more complex embodiment, the control data and / or the

Identification signal include more extensive parameters, so that, for example

Time windows can be defined in which a screen output of sequences is requested. The time windows correspond to a time window during the execution of operating steps in the operating process. In addition, other parameters can be determined, for example, define how the screen output is to be output. For example, here are zoom presets, specifications for a

Level of detail, which is particularly useful for increasing or decreasing the level of detail (resolution) in animations.

In the following detailed description of the figures, non-limiting exemplary embodiments with their features and further advantages will be discussed with reference to the drawing.

DETAILED DESCRIPTION OF THE FIGURES

The invention improves the man-machine interface in terms of Aufrüstzeit, the operating time and freedom from errors. Due to the state-specific generation of a screen output ba with a detailed display of required operating steps, application errors can be avoided.

In the following, the invention will be described in more detail with reference to the figures.

Figure 1 is a schematic representation of an electronic or computer-based calculation unit B for calculating a screen output for a monitor M of a dialysis machine DG or other medical device. The calculation unit B comprises a processor P for data processing. In a preferred embodiment, the calculation unit B comprises three different interfaces: one

Monitor interface mSS, an interaction interface iSS and an image interface bSS. The processor is used to calculate the screen output ba, via the

Monitor interface MSS is sent to the monitor M of the dialysis machine DG. To calculate the screen output ba, the calculation unit B requires several

Input data. The input data may be an identification signal is and / or control data sd. The control data sd and the identification signal is over a common interface, in particular the interaction interface iSS are detected. The interaction interface iSS is preferably designed without contact and can be designed as a gesture interface or as a voice input interface. The interaction interface iSS is a user interface. The data acquired via the interaction interface iSS are forwarded to the processor P for the purpose of processing. In an alternative embodiment, it is possible for the control data sd to be detected on a different interface than the identification signal is. Moreover, it is possible that the control data sd on the processor P of the

Calculation unit B are calculated. The identification signal may be formed as a data record for addressing a memory address in a graphics memory MEM. In this case, with the identification signal is directly to an address in the

Graphics memory MEM are accessed. Alternatively, the identification signal is may be formed more complex and include a data set that identifies, for example, certain parameters of metadata. In this case, the acquired metadata is forwarded to the processor P, which then determines an identification signal according to predetermined rules that can be derived from a rule base (not shown in FIG. 1). The processor then accesses by means of the identification signal is

Graph memory MEM to in order to identify a sequence or a set of sequences from the set of sequences seq stored there and to transmit as an identified sequence iseq to the processor unit P. The processor P can after receiving the identified sequence or the amount of identified sequences iseq the

Calculate screen output ba and forward them via the monitor interface mSS to the monitor M. The calculated screen output ba can then be displayed on the monitor M. In the embodiment of Figure 1, the dialysis machine DG is formed as a separate entity. This has the advantage that the respective user can for example use a user-specific monitor M, for example his mobile device or another mobile device on which an application is implemented in order to accomplish the data exchange with the calculation unit B on the one hand and on the other hand the control signals via the Monitor interface mSS to display the screen output ba to receive. The graphics memory MEM comprises a set of different image sequences, which may be formed, for example, as videos or animations or as a sequence of individual images. In the individual image sequences different operating actions for the dialysis machine DG are stored. They may relate, for example, to an upgrade of the medical device, to operation and / or maintenance of the dialysis machine DG. In this case, an image sequence can be designed as video. It is essential that the image sequences are not monolithic in the graphics memory MEM

are stored but are preprocessed. Each video is preferably decomposed by a method of non-linear editing into a sequence of sequences. Thus, a first image sequence may comprise the following sequences: seq1_1, seq1_2, ... seq1 ... n. A second image sequence may comprise the following sequences: seq2_1, seq2_2, ... seq2_3). An mth image sequence may comprise the following sequences: seqm_1, seqm_2, ... seqm_n. In this case, a sequence can represent a single operating step or a set of operating steps. The extraction of sequences from a sequence can after

different measures take place. For this purpose, a rule base can be accessed which determines the specifications according to which a sequence of pictures is to be broken down.

This has the advantage that the user has the respective handling instruction,

Installation instructions, the tutorial and / or the other supporting notes during the execution of the operating steps on the dialysis machine DG can be adapted individually to the operating progress. Thus, it is no longer necessary to stop a monolithic video and to rewind by hand, to bring the respective operating step repeatedly to the display. By dividing the video into sequences, it is easy to display the respective sequence seq separately and independently of the other sequences for specific control data sd.

FIG. 2 shows a further exemplary embodiment for a connection of the calculation unit B to the dialysis machine DG. The calculation unit B is formed again in accordance with the example shown in Figure 1 with three interfaces. Of the

Monitor interface mSS, the interaction interface iSS and the image interface bSS.

The calculated screen output ba is transmitted to the monitor M of the dialysis machine DG via the monitor interface mSS. In this case, the monitor M is for

Screen output integrated into the dialysis machine DG. It may therefore be in particular the operating monitor M of the dialysis machine DG. The calculation unit B accesses the graphic memory MEM for detecting the identified sequences iseq in order to calculate the screen output ba on the basis of the identified sequences iseq and the control data sd. As shown schematically in Figure 2, the dialysis machine DG additionally comprises a sensor unit S, which may consist of several different sensor types (for example, position sensors, pressure sensors, optical sensors, etc.). The sensor unit S is used for the detection of sensor data se, which via the interaction interface iSS to the

Processor P of the calculation unit B can be forwarded. The sensor data se characterize an operating state of the dialysis machine DG and in particular one Condition during operation. Thus, it can be automatically detected which steps have already been performed for operating the device and which still have to be performed. Based on the detected sensor data se, the processor P can calculate the identification signal is by accessing a database. The identification signal is in turn used to access the graphics memory MEM to deduce the relevant sequences to dynamically calculate the screen output ba.

FIG. 3 shows a further exemplary embodiment, in which the graphics memory MEM is integrated into the calculation unit B. In accordance with the embodiment illustrated in FIG. 2, the monitor M is for outputting the dynamically generated

Screen output ba is determined, designed as a monitor of the dialysis machine DG and integrated into the same. In contrast to the embodiments described so far, however, the interaction interface iSS is also implemented on the dialysis machine DG. The interaction interface iSS can be designed, for example, as a user interface on a touch-sensitive display (of the monitor M) (marked by the solid line in FIG. 3). Alternatively, at least part of the

Interaction interface iSS be designed for contactless detection of interaction signals, and be designed for example as a footswitch or as a gesture interface (shown in Fig. 3 with the dotted lines). The interaction interface iSS can be designed to receive control data sd and / or an identification signal is forwarded to the calculation unit B, which receives these interaction signals via an interface (eg via the bidirectionally designed monitor interface mSS) and then accessing the graphics memory MEM dynamically generates the screen output ba and transfers it to the same via the monitor interface mSS on the dialysis machine DG.

Another embodiment is shown in FIG. Here are all components of the image support system, in particular the monitor M, the calculation unit B and the graphics memory MEM integrated into the dialysis machine DG. In this example, the

Interaction interface iSS as a graphical user interface on the

touch-sensitive monitor M is formed. However, the aforementioned alternative embodiments are conceivable in which the interaction interface iSS can also be embodied in the form of another non-contact interface and serves to receive gestures in order to configure the screen output ba to be generated dynamically. The configuration of the system is flexible, so that the functionalities described can also be distributed to the components in a different structure. Thus, in the illustrated in Fig. 4 Embodiment of the invention, for example, alternatively, only the graphics memory MEM outsourced as a separate module and be addressed via appropriate interfaces.

FIG. 5 shows in a schematic representation that the image sequence (ie the video) is not stored as a monolithic file in the graphic memory MEM, but in image sequence subsequences seq, which can be addressed by the calculation unit B in a dedicated manner. For this purpose, a command for the access is detected, which can be configured as an identification signal is. This accesses a register number, which in Figure 5 the

Regnr bears. With the register number regnr, a targeted access to an element of a register file d can be executed in order to address a specific address field adr. The memory can then be accessed via the address field adr in order to detect the specific operand or the content and in this case the identified sequence iseq, which is transmitted to the processor P of the calculation unit B. Depending on the implementation, the address adr may refer, either directly or indirectly, to the element in memory. As shown schematically on the right side in FIG. 5, a memory element may comprise an assignment from the respective sequence seq and a further data record, in particular from metadata MD. The metadata MD is stored in an associated manner with the respective sequence. Thus, a sequence seq1_1 is assigned the set of metadata a, b, c, and the sequence seq2_1 is the set of metadata a, dd. e and the sequence seqn_m is assigned the set of metadata a, f. This makes it possible, a sequence also on the specification of parameters to the

To identify metadata MD. The access to the sequences seq in the graphic memory MEM is optional. The memory MEM can be a physical memory or a virtual memory. It is also possible that the graphics memory MEM the

Dialysis machine DG assigned or integrated in this.

In connection with FIG. 6, a sequence according to FIG

Embodiment explained in more detail.

After the start of the method, an identification signal for identifying a sequence seq in the image sequence is provided in step S1. The identification signal is either input manually via a user interface (for example, interaction interface iSS) or it can be automatically calculated from existing data. For the calculation of the identification signal is again several possibilities are provided. The identification signal is can for example be calculated directly from the control data sd. It is also possible to calculate the identification signal is from metadata MD to calculate, which can be entered via a user interface. In step S2, control data sd for controlling the screen output ba is detected. This can preferably be done via a non-contact interface, for example the

Interaction interface iSS done.

Thereupon, the calculation unit B accesses the graphics memory MEM with the provided identification signal is in order to directly and specifically address the sequence to be identified, ieeq, in the image sequence. This is done in step S3. In the following step S4, the identified sequence iseq is read in on the calculation unit B.

In step S5, after receiving the identified sequence iseq, the screen output ba can be calculated dynamically on the processor P of the calculation unit B. For this purpose, the read-in identified sequence iseq is used to dynamically calculate the screen output ba on the basis of the provided control data sd and via the

Monitor interface mSS to the monitor M.

Since the complete instructions for operating assistance are advantageously subdivided into subsections (sequences seq), it is possible to arrive at the next sequence seq by displaying a sequence seq on the monitor M by means of a corresponding trigger signal (footswitch actuation, arrow key, gesture). The switching from one sequence to the next can also be done automatically by the sensor unit S on the dialysis machine DG directly detects the operating state and automatically those

Sequences identified for each operating state with the next

Operating steps are relevant. For example, if a sensor of the sensor unit S detects that an alpha clip has been pressed in at the blood pump, then the associated sequence to be subsequently used can be automatically identified.

Preferably, the sequences seq are stored in a GIF format.

In a preferred embodiment, the sensor unit S additionally comprises a

Timekeeping. This makes it possible to measure the execution time for the individual operating steps. The measured execution time per operating step becomes a digital one

Processing unit supplied. As soon as it is determined that a longer time interval is necessary for carrying out the operating steps, a corresponding time can be automatically set

Control signal of the control data sd are generated to instruct the calculation unit B to slow down the displayed sequence seq. This can be the

Screen output ba dynamically to the temporal progress of the operation of the

User without the user having to enter user input. Otherwise, if the user performs the operations faster, this can are also detected, which generates a corresponding control signal to accelerate the dynamic screen output ba play.

In the first case, ie, if a slower execution is detected, additional help measures can be initiated in addition, for example, the screen output ba include an additional element that serves to query the user, if he further supportive instructions (for example, in text and / or Sound) wishes. If the user confirms this via a corresponding user input, measures are automatically triggered to output further instructions in conjunction with the respective operating step. The instructions can be output in graphical, textual and / or auditory form. In addition, it is possible to access a knowledge database via another network interface in order to derive further assistance.

In a preferred embodiment, the generation of the screen output ba is dynamic and regulated. The latter refers to the fact that the user can also enter control data sd during the screen output ba in order to regulate the screen output ba and adapt it to his needs. In particular, he can accelerate or slow down the screen output ba. The control option is based on the respectively identified sequence iseq. In other words, they can be different

Regulations for the different sequences seq are taken, which increases the overall flexibility of the process.

In a preferred embodiment of the invention, it is provided that the dynamically generated screen output ba comprises a sequence of identified sequences iseq. In this sequence of identified sequences iseq additional trigger points can be set to detect trigger signals from the user to control the further screen output ba. For example, it can be determined at a trigger point that the preceding sequence is repeated again or it can be determined that the following sequence should be displayed. At the trigger point, it may also be determined to jump to any subsequent sequence and thus skip other sequences. In other words, the trigger points are used to acquire control data sd, which are preferably detected contactless again in order to minimize the risk of germ transmission as far as possible.

In a further embodiment, the control data sd may also be configured to determine whether the identified sequences iseq only in one visual format (visual display only) or in addition to be played with sound data. The reproduction of the identified video sequence iseq without sound can prove to be particularly useful if the dialysis machine DG in a

Dialysis center (several dialysis DG in a room in which there are already patients) should be applied to keep the noise as low as possible.

Finally, it should be noted that the description of the invention and the

Embodiments are not to be understood as limiting in terms of a particular physical realization of the invention. All of the features explained and shown in connection with individual embodiments of the invention may be provided in different combinations in the article according to the invention in order to simultaneously realize their advantageous effects. Thus it is e.g. It is also within the scope of the invention to provide, in addition to the interaction interface, other interfaces for the acquisition of the input data for the calculation unit B. In particular, it will be apparent to one skilled in the art that the invention can be applied not only to dialysis machines (e.g., a hemodialysis machine or a peritoneal dialysis machine), but also to other medical devices that need to be operated via a dynamically controlled screen output ba.

Furthermore, the components of the medical device DG for state-dependent control of the medical device DG via an adaptively generated screen output ba distributed to several physical products can be realized.

The scope of the present invention is given by the claims and is not limited by the features illustrated in the specification or shown in the figures.
